Abstract

The experiment was carried out to study the quality evolution of Jonagored apples (Mallus domestica cv. Borkh) during 14 days of shelf life prior to controlled atmosphere (CA) storage. The apple were harvested from the “Fruitteelt centrum” (Velm, Belgium) in 24 September 2010 (optimal picking) and 8 October 2010 (late picking) and were stored at 18°C and 65% RH to mimic the shelf life condition. The apple then were measured for colour, firmness, soluble solid content (SSC), titratable acidity, ethylene production rate, O 2 consumption rate, CO 2 production rate and respiratory quotient (RQ) at 0, 7 and 14 days after harvest. There was a significant effect of shelf life duration in colour of the apple. The apple turn its colour from green to yellowish green at the end of shelf life. The optimal-harvested apple had a greener colour than the late-harvested apple at 0 and 7 days of shelf life except at 14 days where the older apple had a greener colour. Although the effect was not consistent, firmness of apple was affected by shelf life and picking time as well. Firmness decreased along shelf life and the optimal-harvested apples were firmer than the late-harvested apple. Apple’s acidity decreased during shelf life from 8,43 mL NaOH (optimal-harvested apple) and 8.85 mL NaOH (late- harvested apple) to 7.58 mL NaOH (optimal-harvested apple) and 7.03 mL NaOH (late- harvested apple) at the end of shelf life. Yet, acidity was not affected by picking time. Ethylene was considerably increased throughout shelf life and the late-harvested apple had a higher ethylene production level than the optimal-harvested apple. Optimal-harvested apple had a lower respiration rate than the late picked apple. Older apple consumed oxygen and produced carbon dioxide at a higher rate than the younger apple. Moreover, respiration rates as represented by O 2 consumption rate, CO 2 production rate and respiratory quotient (RQ) tended to increase along shelf life.

Abstract

One potential source of essential oils in Bali which has not been developed is from cendana frangipani flower. Cendana frangipani flower has a very distinctive scent and very popular in Bali, it has an important function in the local culture, used as fragrances, incense (prayer facilities especially in Bali), and as an air freshener aromatherapy in the spa industry. The fragrance is typical due to their volatile oil which content in the cendana frangipani flower. The quality produced of essential oils are determined by their chemical composition of the extraction process. Previous research indicates that the good quality of frangipani immature essential oil extractedthrough the extraction process using hexane resulting in concrete form which still has the solvent aroma, semi-solid consistency and dark yellow. Therefore, it is necessary tomodifythe process by changing the concrete into the absolute product by re- extraction using ethanol.The purpose of this study was to determine the differences in chemical composition of essential oils of cendana frangipani flowers resulting from the re-extraction by using a particular comparison between ethanol and concrete. Fresh cendana frangipani flowers were sliced and then extracted with n-hexane in a Soxhlet extractor toproduce concrete volatile oil. The concrete was further re-extracted using absolute ethanol to produce essential oil with a concrete and ethanol comparison treatment consisting of 1:4, 1:6, 1:8, and 1:10. Absolute essential oil were then analyzed by GC-MS. The analysis showed that the absolute cendana frangipani flower essential oil produced by different treatment has a different compounds composition and relative percentages varied. The chemical composition of cendana frangipani absolute essential oils was classified as alcohols, terpenes, ketones, esters, and acid with the concentration from 2.65 to 24.77%;0.34 to 1.35%; 0 to 1.38 %; 13.38 to 24.23% and from 22.74 to 58.15% respectively.

Abstract

The study aims to analyze the performance of the inventory control and agroindustry development strategy banana chips. Site selection was done in the chips industry center Bandar Lampung City. Sampling was done offender census on members of banana agroindustry business group. Data analysis methods used was the analysis of economic order quantity (EOQ), SWOT and AHP. The results showed that the control of inventory through the ordering of raw materials and production capacity adjusted to do with intersystem messaging. The production process is generally carried out every 3 times a week with raw material price of Rp 3500,- per comb. Agroindustry development strategy banana chips were utilizing fabric of cooperation with other parties in the application of science and technology in order to produce quality products, banana chips, giving a sense of innovation so that the amount of consumer interest and increasing demand for banana chip, and optimization of infrastructure and facilities wereowned agroindustries effective and efficient.

Abstract

The high nitrogen content in the wastewater can also inhibit the performance of microorganisms. It can be overcome by Membrane Bioreactor (MBR) combined with anoxic tanks. Use of membrane can be set aside and the organic materials with high concentrations of nitrogen. From this research are expected to know the influence of various concentrations of Mixed Liquor Suspended Solid (MLSS) and Chemical Oxygen Demand (COD) on the performance of the MBR to eliminate the organic materials and nitrogen in the anoxic condition. This study used activated sludge from wastewater treatment Surabaya Industrial Estate Rungkut (SIER) as an inoculant and 'synthetic' wastewater as the MBR influent. Research variable is the concentration of COD in mg/L and Sludge Retention Time (SRT). The results showed that the overall performance of the MBR is relatively stable and good. % COD removal obtained at the highest permeate COD concentration of 1800 mg/L, reaching 90%. Total number N in permeate is smaller than 0.5 of the amount of total N in influent or % removal > 50%, then the process of denitrification can be said to be successful. For turbidity removal reached 98.47 up to 98.85%. The flux is getting dropped because fouling due to particles that accumulate on the surface layer of the membrane .

Abstract

Nagoyaramen is a franchise ramen restaurant. Nagoyaramen was switching business location, so they needed information about target and market segments which would affect the marketing strategy. The purpose of the study was (1) Analyzing and defining market segments of Nagoyaramen. (2) Formulating marketing strategies of Nagoyaramen in accordance with the selected segment. The primary data collection was done through questionnaire. This study used descriptive analysis such as Importance-Performance Analysis method and cluster analysis. Interview was used to choose the best strategy. Cluster analysis resulted in dividing costumers into three segments, namely a perfectionist, tasteful, and socialist. We picked the perfectionist which covers 60.66% of customer. This particular segment is concerned with almost all attributes of marketing mix. The group was predominantly female (71.43%), work as a student (45.05%), age range 17-24 years (52.75%), and last education high school (43.96%). Strategies offered are location approaching schools or colleges, affordable prices, promotion through fliers and giving discounts, Japanese ornaments must remain there as a hallmark of Nagoyaramen, Japanese ornament on the nameplate, taste of the product should be maintained, maintaining a varied menu, and speeding up the service around lunch break. So the best strategy chosen by the owner is location approaching schools or colleges.
